But Abedin has since renewed the lease on their pricey Union Square duplex — and invited back home the man who has repeatedly heaped humiliation upon her, sources told The Post.

The luxury three-bedroom, 1,500-square-foot pad at 1 Irving Place features an “expansive, panoramic view of Union Square Park and the midtown skyline,” according to a Corcoran listing.

The sext-crazed pol, who had been sleeping on his mother’s couch in Park Slope, was to move out Tuesday, a source said.

“He was supposed to move,” the building source explained. “But they just signed for another year.”

Another source said, “She still hasn’t served him with the divorce papers.”

Weiner, who will have to register as a sex offender as part of the plea deal with the Manhattan US Attorney’s Office, was spotted Tuesday at about 9 a.m. strolling out of the building with his and Abedin’s 5-year-old son.

A pal of the couple said Weiner has been the primary caretaker for the boy, especially while Abedin worked on Clinton’s failed presidential bid.

“Huma is worried about her son,” the pal said. “That’s her priority, and Anthony plays a very strong role in raising him.”

It’s unclear whether Abedin, 41, is on the $11,900-a-month lease alone or signed with Weiner, who is scheduled to be sentenced Sept. 8.

Brokers could not discuss the leasing arrangement because they signed a strict nondisclosure agreement. “We are really worried about this one,” a broker said. “This is a very sensitive rental.”

“I have a sickness but I do not have an excuse,” he told federal Judge Loretta Preska between sobs. “I knew that was morally wrong.” Abedin was not in the courtroom.

Weiner’s creepy behavior may have even played a role in the 2016 presidential election. The FBI opened an inquiry into Weiner’s conduct in September and seized his laptop and phones, leading the feds to realize some of Clinton’s emails were on his computer. Then-FBI Director James Comey told Congress he would reopen an investigation into Clinton’s private email server two weeks before the election as a result.

Weiner has long been plagued by a weakness for sexually charged cyber correspondence. The Post reported in August 2016 that he was still sexting women, prompting his wife to announce their separation.

He had texted a crotch shot to a West Coast mom that included his then-3-year-old in bed next to him.

He entered outpatient therapy for sex addiction in Tennessee last fall, where a Post reporter and photographer spotted him riding a horse as part of his treatment.

The Weiner sexting scandal began in 2011 when the then-up-and-coming congressman accidentally tweeted a picture of his bulging member out to the public and then claimed his account had been hacked. Eventually, he came clean and resigned from office.

He tried to revive his political career in 2013, running for New York mayor. But the campaign was quickly derailed when 22-year-old Syndey Leathers came forward with proof of their online relationship. Revelations of other online sexting partners soon followed.
